What problem does it solve?

Sage's checkpoint system provides deterministic state capture and safe recovery to support undo/rollback in long-running tasks. It enables reproducible experiments and safe transactional operations by saving comprehensive state, file changes, and conversation context to allow precise restoration.

Core Features & Use Cases

• State snapshots: capture complete execution state for safe restoration.
• File tracking: monitor and restore file changes across checkpoints.
• Diff and rollback: compute diffs and rollback to a chosen checkpoint.
• Session and tool integration: manage per-session and tool-execution checkpoints for reliable workflows.
• Use Case: before applying risky config changes, create a checkpoint, perform changes, and revert if needed.

Quick Start

Create a manual checkpoint: sage checkpoint create --type Manual --description 'Before risky update'.
